-Analog inputs provide various ways to measure real analog data from external systems. The Analog Discovery Studio has two analog input channels, each of which can be used with either BNC cables or MTE flywires, selectable with switches. When used with BNC cables, the analog input channels are single ended (FIXME although any circuit/s they are connected to should share a ground with the ADS). When used with MTE flywires, the analog input channels are differential...+===== Oscilloscope =====
  
-The Analog ​Input Channels ​are shared ​by Waveforms' FIXME instruments.+FIXME image - screenshot of scope instrument 
 + 
 +The Analog ​Discovery Studio can be used with WaveForms'​ Oscilloscope instrument to capture analog input data via the analog input ("​Scope"​) channels, using either BNC cables or MTE cables. When this instrument is used, the Analog Discovery Studio'​s analog input channels act as a two-channel,​ 14-bit, 100 MS/s oscilloscope. 
 + 
 +When used with BNC cables, the oscilloscope channels are single-ended,​ however, the circuit under test must still share a common ground with the Analog Discovery Studio. With BNC cables, the analog input channels have a bandwidth of 30+ MHz. 
 + 
 +When used with MTE cables, the oscilloscope channels'​ **+** and **-** pins are differentially paired. The **-** pins can be attached to a non-ground circuit net, but the circuit under test must still share a common ground with the Analog Discovery Studio. With MTE cables, the analog input channels have a bandwidth of 9 MHz. 
 + 
 +Since the Analog Discovery Studio'​s analog input channels ​are shared, the Oscilloscope instrument cannot be used at the same time as the Voltmeter, Data Logger, Spectrum Analyzer, Network Analyzer, or Impedance Analyzer instruments. 
 + 
 +For more information on the analog input ("​Scope"​) channels, please visit the **Analog Discovery Studio Specifications**. For a walkthrough of the different features of WaveForms' ​Oscilloscope instrument, please visit the **Using the Oscilloscope** guide. ​FIXME links. 
 + 
 +--> Important Note: Grounding Circuitry # 
 + 
 +Despite the fact that the Analog Discovery Studio analog input channels are fully differential,​ a GND connection to the circuit under test is required to provide a stable common mode voltage. 
 + 
 +The Analog Discovery Studio'​s GND reference is connected to the USB GND. Depending on the PC powering scheme, and other PC connections (Ethernet, audio, etc. – which might also be grounded) the Analog Discovery Studio GND reference might be connected to the whole GND system and ultimately to the power network protection (earth ground). The circuit under test might also be connected to earth or possibly floating. 
 + 
 +For safety reasons, it is the user’s responsibility to understand the powering and grounding scheme, and to make sure that there is a common GND reference between the Analog Discovery Studio and the circuit under test, and that the common mode and differential voltages do not exceed specifications. Furthermore,​ for distortion-free measurements,​ the common mode and differential voltages need to meet specifications.

 +===== Waveform Generator =====
 +
 +FIXME image - screenshot of wavegen instrument
 +
 +The Analog Discovery Studio can be used with WaveForms'​ Waveform Generator instrument to output analog voltage waves via either BNC cables or MTE cables. The Waveform Generator converts 14-bit digital samples to analog at a rate of up to 100 MS/s on each of two channels. When the Waveform Generator instrument is used, the Analog Discovery Studio'​s analog output channels act as an Arbitrary Waveform Generator. The instrument supports everything from simple waveforms like Sine and Triangle waves, up to more complicated functions like AM and FM modulation. Custom sets of samples can be defined by the user in applications like Excel and imported to WaveForms.
 +
 +Each waveform generator channel is considered a single ended pin, however, a connected circuit must share a ground with the Analog Discovery Studio. Each channel has a bandwidth of 8MHz through both the BNC and MTE connectors. AC amplitudes of +-5V and DC offsets of +-5V are supported.
 +
 +Since the Analog Discovery Studio'​s analog output channels are shared, the Waveform Generator instrument cannot be used at the same time as the Network Analyzer, or Impedance Analyzer instruments.
 +
